Manual page for available_variables(PL)
DESCRIPTION
Ploticus scripts may contain variables.
These variables may be set within the script or by the user on
the command line. See
variables
This page describes many of the variables that
are automatically declared and set by ploticus at run time.
These may be accessed by your scripts if necessary.
These variables may be referenced beginning with the proc
following the setting proc.
Ploticus is not affected if you #declare or #set them
or use these names for other purposes.
Note that in order to reference a variable immediately after the
proc which set it, #proc endproc must be used.
It is possible that there are recently added variables
that are not summarized here; please check the proc man page
for complete information.
VARIABLES
AREALEFT AREARIGHT AREABOTTOM AREATOP
Set by proc areadef to the locations of the current plot area edges in
absolute units.
.
XMIN XMAX YMIN YMAX
Set by proc areadef to the limits in scaled units, of the plotting area.
DATAXMIN, DATAXMAX
The minima and maxima of the data field when xautorange is used.
Different from XMIN and XMAX in that these do not include any margin.
DATAYMIN, DATAYMAX
The minima and maxima of the data field when yautorange is used.
Different from YMIN and YMAX in that these do not include any margin.
DEVICE

NFIELDS
the number of fields per record in the current data set.
NRECORDS
the number of records in the current data set.
NVALUES

proc scatterplot or proc rangebar.
May be used in the proc scatterplot legend label.
RANGEBARMEDIAN RANGEBARMIN RANGEBARMAX
the median, min, and max value of the most recently drawn rangebar,
in scaled units.
TOTALS
